Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units? a. h(x) = 3x + 4 b. h(x) = -3x + 4 c. h(x) = 3x-4 d. h(x) = -3x+4

D.

Step-by-step explanation:

we are given

Firstly, it is reflected over x-axis

we know that for reflection about x-axis , we can replace y as -y

we get

now, it is vertical shift up by 4 units

so, we can add 4 to y-value

we get

a)(x-2)^2+(y-1)^2=9
